发明名称 Detergent and method for producing the same
摘要 The invention is directed to a detergent and a method of producing the same. The detergent is for textile surfaces and especially for textile floor coverings. The detergent includes a pulverized, porous carrier including a foamed, plastified urea-formaldehyde resin foam. The carrier material is enriched with detergent so that the finished product with respect to the carrier material has a weight per unit volume of 60 kg/m3 and an apparent density of 50 to 150 grams/liter; the granular size of the carrier material is between 0.01 and 12 mm; the surfactant containing water, which adheres to the carrier material, is stored in the carrier material in a completely homogeneous manner in a share of maximally 80% by weight referred to the weight of the carrier material; and, the detergent is produced from the mixture of the carrier material with a highly concentrated aqueous cleaning solution. The method includes the steps of foaming the plastified urea-formaldehyde resin foam; and, combining the free formaldehyde present during the manufacturing process prior to and/or during the foaming of the plastified urea-formaldehyde resin foam by adding formaldehyde binding substances and stabilizing substances to at least one of the solutions selected from the group consisting of the foaming agent solution and the resin solution.
